Hey all 👋 — I sent this to the mailing list as well but I wanted to highlight the issue here as well since it could be a pretty big blocker 😅 : issues.apache.org/jira/browse/FLINK-37686 We ran into this last night and from what I can tell all impacted classes are unchanged across all Flink releases. I tried to collect my findings into the comment on this issue and I would be happy to help out with a fix here. Thanks!
